Black-faced Grosbeak
Caryothraustes poliogaster
Rather chunky, social bird of humid evergreen forest and edge in tropical lowlands and foothills. Usually in small and often noisy groups (at times up to 50 birds), moving at middle to upper levels in fruiting trees; not usually with mixed-species feeding flocks. Sexes look alike, with subtly attractive plumage: mustard-yellow head and breast with black face and blue-gray belly. Calls are buzzy splutters and whistles.
Identification
The adult black-faced grosbeak is 16.5 cm long, weighs 36 g, and has a heavy, mainly black, bill. It has a black face, yellow head, neck and breast, and olive back, wings and tail. The rump and belly are grey. Immatures are duller and have duskier face markings. The vocalisations include sharp chip or tweet calls, buzzes and whistles, and the song is a musical whistled cher chi weet, cher chir weet, cher chi chuweet.

Other Birds
Ash-browed Spinetail
Cranioleuca curtata
Fairly small rufous-brown bird found on the east slope of the Andes from Colombia to Bolivia. Wings and tail are bright rufous, contrasting with duller brown body and head. Note rufous cap and slightly paler eyebrow. Compare with Red-faced Spinetail, which has entirely rufous cheek and crown. Look for singles or pairs in the middle levels and canopy of montane forest and edge from around 900 to 2,000 m. Forages with mixed-species flocks, hitching along branches and probing into patches of moss and clumps of dead leaves.
Eastern Violet-backed Sunbird
Anthreptes orientalis
A fairly small sunbird with an unusually short, warbler-like bill. The male has an iridescent violet head and back, while the female has brownish upperparts, white underparts, and a white eyebrow. Found in dry thorn savanna and thorn scrub, often in pairs. Very similar to Western Violet-backed Sunbird, but in the area of overlap, Eastern is separated by the male’s turquoise rather than violet rump, and by the female’s pure white rather than yellow-tinged belly. Also similar to Uluguru Violet-backed Sunbird, but found in different habitats, and separated by the white rather than gray underparts of the male and the white eyebrow of the female. Vocalizations include a scolding mew and a high-pitched jumbled song.
Chilean Woodstar
Eulidia yarrellii
Tiny, highly endangered hummingbird found very locally in the desert of northern Chile. Favors native desert scrub in lowland valleys, but widely eliminated from most areas by intensive agriculture. Male most often detected by insectlike buzz made by wings in flight. Also perches conspicuously atop bushes and on wires; note diagnostic crossed tail feathers. Female similar to Peruvian Sheartail, but has shorter tail with pale rusty bases to outer feathers (hard to see).
